With the coming of Intel’s 12th-generation Core processor code-named Alder Lake getting closer, foreign media even exposed relevant specifications, Benchmark test results and prices. Judging from this information, it is likely that Intel has achieved the largest increase in performance across generations in recent years.

According to the information announced by Intel on Architecture Day 2021 (Architecture Day 2021), we know that Alder Lake processors are powered by Performance Core (P-Core) code-named Golden Cove and Efficient Core (E-Core) code-named Gracemont The efficiency core is composed of two cores.
The highest-end Core i9-12900K has 8 P-Cores and 8 E-Cores, which can provide a total of 16 cores/24 threads, with a 30MB L3 cache. P-Core all-core Boost clock can reach 5.0 GHz, single-core Boost can reach up to 5.3 GHz; E-Core all-core Boost clock can reach 3.7 GHz, up to 3.9 GHz.
After all, the Core i9-12900K is an overclocked version. The PL1 TDP is set to 125W, and the PL2 TDP can reach 228W. The estimated price is US$599. The retail price of the box leaked by the distributor is US$604.89. The Core i9-12900KF box without internal display The retail price is US$578.13.
The base clock of the non-overclocked Core i9-12900 should be lower. The PL1 TDP is set to 65W, and the PL2 TDP is about 200W. The estimated price is US$509.
The second-tier Core i7-12700K has 8 P-Cores, but the E-Cores are reduced to 4, providing a total of 12 cores/20 threads, with 25MB L3 cache. P-Core all-core Boost clock can reach 4.7 GHz, single-core Boost can reach up to 5.0 GHz; E-Core all-core Boost clock can reach 3.6 GHz, up to 3.8 GHz.
The overclocked version of the Core i7-12700K has the same TDP settings as the Core i9-12900K, PL1 125W, PL2 228W, and an estimated price of US$429. The US distributor Provantage leaked a boxed retail price of US$422.17. Core i7- without internal display. The retail price of the 12700KF box is US$395.61.
The non-overclocked version of Core i7-12700 has a lower base clock, TDP PL1 / PL2 are 65W / 200W respectively, and the estimated price is US$359.
The first-tier Core i5-12600K further reduces the number of P-Cores to 6, and the number of E-Cores is maintained at 4. It can provide a total of 10 cores / 16 threads, with 20MB of L3 cache. P-Core all-core Boost clock can reach 4.5 GHz, single-core Boost can reach up to 4.9 GHz; E-Core all-core Boost clock can reach 3.4 GHz, up to 3.6 GHz.
The overclocked Core i5-12600K has a TDP PL1 / PL2 of 125W / 228W. The estimated price is US$279. The retail price of the box leaked by distributors is US$288.77, and the retail price of the Core i5-12600KF without internal display is US$288.77. US$261.77.
Core i5-12600 / i5-12400
The more entry-level models are Core i5-12600 / i5-12400. At present, it is only known that it has 6 P-Cores and no E-Cores. It can provide a total of 6 cores / 12 threads. TDP PL1 / PL2 are 65W respectively. / 200W, the estimated price is US$249 / US$203 respectively.
Engineering version sample performance
First of all, from the familiar Cinebench R23 rendering operation, Intel Alder Lake CPU single-core performance is really a big win, leading rival products of the same level by at least 20%. In terms of multi-core, Core i9-12900KF is equivalent to AMD Ryzen 9 5950X, Core i7-12700KF is faster than Ryzen 9 5900X, and Core i5-12600KF is faster than Ryzen 7 5800X.
In the Blender rendering test, Core i9-12900KF is between Ryzen 9 5900X / 5950X, but closer to Ryzen 9 5950X. Core i7-12700KF is close to Ryzen 9 5900X, while Core i5-12600KF is faster than Ryzen 7 5800X.
In the video encoding test, Core i9-12900KF is faster than Ryzen 9 5950X in X264 and X265 HD, but it lost in the HWBOT X265 test. Core i7-12700KF has similar performance to Ryzen 9 5900X, and Core i5-12600KF has similar performance to Ryzen 7 5800X.
However, in the PCMark test, Alder Lake CPUs all lost to rival products at the same price, and even lost to the previous generation of Rocket Lake CPUs. However, due to the early days, it is temporarily impossible to confirm that these tests are performed on Windows 10 or Windows 11, and the support of PCMark for new processors.
Of course, since the product has not yet been officially released, there are still some variables in the final performance. But if the engineering version samples have such excellent performance, we can really look forward to the days when Intel will overtake its opponents. After all, competition can make progress.
